APPARATUS FOR DISPOSAL OF WASTE ROCK FROM CONCENTRATING-MILLS AND THE LIKE.

Specification of ietters Patent.

Application filed April 13, 1911.

Patented Sept. 12, 1911. Serial No. 620,750.

To all whom it may concern:

Be it known that I, HENRY R. VVAHL, a citizen of the United States, residing at the city of Elvins, in the county of St. Francois and State of Missouri, have invented certain new and useful Improvements in Apparatus for Disposal of Waste Rock from Concentrating-Mills and the Like, of which the following is a specification.

This invention relates to portable railways, and it comprehends an improved apparatus especially designed for use in disposing of waste rock, or other material, from mines, concentrating mills for lead ore, or other places.

In the drawings forming part of this specification, like numbers of reference denote like parts wherever they occur, and Figure 1 is a plan view of the complete apparatus; Fig. 2 is a side elevation of same; Fig. 3 is a sectional view on the line 33, Fig. 1; Fig. A, is a sectional view on the line 44l-, Fig. 1; Fig. 5 is a sectional view on the line 55, Fig. 4:; Fig. 6 is a sectional view on the line 66, Fig. 3; Fig. 7 is a plan view of means for regulating the tension of one of the conveyors; Fig. 8 is a perspective view of a valve for one of the discharge pipes; Fig. 9 is a bottom plan view of one of the discharge pipes; Fig. 10 is a sectional view on the line 1010, Fig. 9; Fig. 11 is a sectional view on the line 11-11, Fig. 10; and Fig. 12 is a plan view of an alternate form of the apparatus.

The framework 1 of a car 2, which is movable upon a comparatively short track 3, supports a bin 4 and, also, the terminal of a track 5, which is located above said bin and which extends to the concentrating mill, mine, or other place where the material to be disposed of is located. Cars 6, preferably of the bottom-discharge type, are operated upon track 5 by means of an electric or steam locomotive (not shown in the drawings) or by any other suitable means. Car 2 is preferably made long enough to allow two or more cars 6 at a time to occupy a position above bin 4:, in order to discharge their contents into same, but, when it is desirable, said car 2 can be made of such length that only one car 6 can occupy a po sition above said bin.

The track 5 is laid upon a fill 7, which terminates at the rear end of track 3.

A portion of track 5 spans the open space between the end of fill 7 and the rear end of car 2 and is supported by means of a pair of girders 8. Each girder 8 is hinged in any suitable manner to the end of car 2, in order to allow the end of same that rests in the fill to move up or down relative'to car 2 when said car'is moved forwardly in the manner hereinafter described.

. A plurality of discharge pipes 9 project from bin 4. Each of said pipes is provided with a valve 10 which is pivoted at 11 to said pipe and which bears a spout 12, and, .when said valve is moved to a position to cause spout 12 to communicate with pipe 9, the material in said pipe passes out through said spout 12. Said valve is connected to an eccentric 13 by means of an arm 14 pivoted at 15 to said valve. Said eccentric 13 bears a clutch member 16, and is loosely mounted on a shaft 17, journaled in journal-boxes 18. A clutch 19 is splined to shaft 17 and is adapted to slide thereon, a lever 20 being arranged to move said clutch into and out of engagement with clutch member 16, in order to cause eccentric 13 to move valve 10 to a position to open or close pipe 9.

Each shaft 17 is provided with a pulley 21. A belt 22 drives pulley 21 and is driven by a pulley 23 on the next shaft 17. A belt 24: drives one of the pulleys 21, and receives its power from a pulley 25 on a shaft 26 journaled in journal-boxes 27, which are supported by means of brackets 28 or the like. A belt 29 receives its power from a motor 30 or other suitable source and drives a pulley 31 on said shaft 26.

A belt conveyer 32 is arranged to receive the material discharged from spouts 1.2. Said conveyer runs on a pair of pulleys 33, and travels in the direction indicated by the arrows in Fig. 3, in order tocause the material carried thereby to be dis charged into a hopper 34: supported by standards 35 or the like at the forward end of car 2. One of the pulleys 33 is mounted on shaft 26, and drives the conveyer 32. The other one of said pulleys 33 is mounted on a shaft 36, which is journaled in ournalboxes 37, each of said journal-boxes being arranged to be adjusted by means of a hand wheel 38 on a screw-threaded rod 39 or other suitable device attached thereto for the purpose of regulating the tension of the belt conveyer 32.

A belt conveyer is arranged to receive the material discharged from hopper 34, and is mounted upon a boom 41. Said boom is supported on a roller-bearing turn-table 42 on the front end of car 2, and is free to swing in aplane more or less horizontal to the horizon through substantially one hundred and eighty degrees, the free end of said boom being supported by means of a guy ,43 which is fastened to van upright of the framework I. Said conveyer 40 runs on a pair of pulleys 44 and travels in the direction indicated by the arrows in Fig. 4 to .eause the material carried thereby. to be discharged at the forward end of boom 41, in orderto make the fill 45 upon which the track 3 is laid. One of the pulleys 44 is mounted on a shaft 46 which is journaled in journal-boxes 47, each of said journalboxes 47 beingarranged to be adjusted by means of a hand-wheel 48 on a screwthreaded rod 49, or other suitable device, for the purpose of regulating the tension of belt conveyer 40. The other one of said pulleys 44 is mounted on a shaft 50 journaledin journal-boxes 51, and drives said conveyer 40. A belt 52 drives pulley 53 on said shaft 5Q,and receives its power from a motor 54 or other suitable driving means, preferably manner oversaid track. A trolley pole 57 1 borne :by framework 1 of car 2 is arranged to engage trolley wire 56 in order to supply motive power to the motors 30 and 54 for the operation of conveyers 32 and 40.

the alternate form depicted in Fig. 12, the car 2 is made sufliciently wide to extend over two parallel tracks 3 and is supported The bin 4, track 5, conveyers 32 and 40,, and boom 41 are in duplicate and are arranged in the manner hereinabove described. A central power station is preferably located on said car 2, and consists of a boiler 58 and engine 59, which operates a dynamo 60, from which electrical motive power is obtained and .conducted to the motors for operating the various moving par-ts. The apparatusis best adapted to operate over sloping ground or over a valley" the commencement of operation being at as high a location as possible. As long' as the difference in elevation between the grade of fill 7 and the grade of the natural ground upon which said fill is made is substantially equal to the difference in elevation between the grade of trackt and the grade of. track 3,- said track 3 is laid upon the natural ground. o

After these preliminaries, theap'paratus is used as follows: Each car 6 is brought to a position over girders S to cause the contents thereof to be dumped between said girders and to be deposited upon the end of fill 7 The material is de )osited in this manner upon the end of fill 7 until same reaches the rear end of track 3. The rail joint at the end of each girder 8 that rests upon the fill 7 is broken and the car 2 is moved forwardly in any suitable manner upon track 3 until same clears the last rail joints of said track 3. Two rails are laid in the space that is made in track 5, when the car 2 is moved forwardly upon track 3, and are connected in the usual manner to the adjoining rails of said track 5. The rear section of track 3 is removed and is laid as the forward section of said track. The material is then deposited upon the end of fill 7 until same reaches the rear end of track 3, and the car 2 is again moved forwardly as hereinabove described. The car 2 is thus moved forwardly until the forward end of boom 41 reaches over the point where the natural ground upon which fill 7 is made slopes downwardly from the grade of track 3. The material is then dumped into bin .4, and the conveyers 32 and 40 are set into operation and the valves 10 are moved in the manner hereinabove described to cause the material to pass through spouts 12 to said conveyer 32. Said conveyer 32 deposits the material carried thereby into hopper 34, which delivers same to the conveyer 40. Said conveyer 40 delivers the material from the forward end of boom 41, which is swung in any suitable manner into position to carry the material to the point desired, and there to dump it. When the material thus deposited reaches the grade of track 3, the car 2 is moved a few feet ahead, and the operation is repeated. After each forward movement of car 2 upon track 3, the boom 41 deposits the material to the extent of its distributing area in order to build the fill or roadbed 45 for track 3. When car 2 is moved forwardly far enough to .clear the last rail joints of said track 3, the rear section of said track is moved to the front end, and the fill 7 is lengthened in the manner hereinabove described.

Once started, this apparatus makes its own roadbed without the necessity of using trestles or false-work, and is capable of filling up almost an entire valley by returning to the original starting point and offsetting the car 2 and track 3 the width of the fill 7.

The operation of the alternate form of the apparatus is substantially the same as the operation of the form just described, with the exception that the moving parts are driven with motive power generated by a central power station located on said car. Due to the duplication of parts in this form,

the apparatus can distribute double the amount of material and over a greater area than is possible with the form of apparatus first described.

I claim:

1. A portable railway comprising, in combination, a track consisting of portable sections, a car movable on said track, and a superimposed track having a terminal thereof supported upon said car, the rearmost section of the first-named track being adapted to be removed after the car has passed therebeyond and placed in front of the foremost section.

2. A portable railway comprising, in combination, a track, a car movable thereon and having a support hinged to its rear end, and a superimposed track having its forward terminal extending along said support and resting upon said car.

8. A portable railway comprising, in combination, a track consisting of portable sections, a car movable on said track and having a support hinged to its rear end, and a superimposed track having its forward terminal extending along said support and resting upon said car, the rearmost section of the firstnamed track being adapted to be moved after the car has passed therebeyond and placed in front of the foremost section.

. In testimony whereof I hereunto afiix my signature in the presence of two witnesses. HENRY R. VVAHL. Witnesses:
